London is well served by three international and domestic airports. Heathrow and Gatwick have good rail connections into the centre of town and the smaller but central City Airport is a short cab ride away from the epicentre of kinkiness that is going on over the weekend. If you are travelling from overseas do check your travel connections into London as tubes and rail tend to have high maintenance schedules over weekends.
